GEORGE W. TURNER, OF BOSTON, MASSACHUSETTS.

MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Application filed January 17, 1581.

To all whom it may concern:

Be it known that I, GEORGE IV. TURNER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and use.- ful Improvements in Mechanical Musical Instruments; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention relates to improvements in mechanical musical instruments of that class in which a perforated traveling sheet is used to regulate the admission of air to reeds or pipes operated by either exhaust or force bellows; and it consists of a hinged or swinging pressure roller or bar so arranged in relation to the perforated sheet and tuheboard that when the end of the perforated sheet passes under the said roller or bar and away from it said roller or bar will automatically doseend and open a valve, thus preventing the instrument from sounding after the end of the perforated sheet has passed by the said roller or bar. During the ordinary use of the instrumerit-that is, when a tune is being played the aforesaid roller or bar is held upward by resting on the movable perforated sheet.

On the accompanying drawings, Figure 1 represents a plan view of the invention 5 and Fig. 2 represents a cross-section on the line A B, shown in Fig. 1.

Similar letters refer to similar parts wher ever they occur on the different parts of the drawings.

The drawings represent a mechanical musical instrument the case of which is removed.

a. is the bellows, and b I) represent the feeders, as usual.

0 is the tube-hoard, with its reeds d d d and channels 0 0, leading to the bellows a, in the ordinary way.

fis the perforated sheet, and g is the feedroll, between which and the pressure-roll h the said sheetis moved by means of the usual crank or other mechanism.

iis the stationary guide for the perforated sheet above the tube-board c, as shown.

It and l are the supports on which the perforated sheet is resting while being fed to the tube-board 0.

Patent No. 243,661, dated June 28, 1881.

(N0 model.)

an represents the roller or bar on the end of the arms a n, which are hinged on the fulcra a it, around which the said bar or roller m is movable.

o is the relief-valve, with its valve-hole 0 and spring 0", for the purpose set forth.

0 is a suitable projection on the relief-valve o, andp is a knee-lever, hinged atp, and adapted to be acted upon by the roller or bar m durin g its descent, so as to automatically open the valve 0 and preventtheinstrumentfrom sounding after the end of the perforated sheet has reached the said bar or roller m, as and for the purpose described.

I desire here to state that I do not confine myself to the use ol'a bar or a loosely-revolving roller, m, in the carrying out of my invention, as either may be used to accomplish the desired result; neither do I confine myself to the exact arrangement of a knee-lever, p, as the intermediate device between the under side of -the bar or roller m and the valve 0, as such may be changed and another and equivalent device substituted without afl'ecting the practical operation of the invention.

I disclaim, in a mechanical musical instrument adapted to be operated by a traveling music-sheet, the combination of a rest, a-roller or rollers upon one side of said rest for drawing the music-sheet forward, and a non-rotary drag-bar upon the other side of said rest, under which the music-sheet passes, as I am not the first inventor thereof.

Having thus fully described the nature, construction, and operation of my invention, I wishzto secure by Letters Patent, and claim- In a mechanical musical instrument, the hinged or swinging roller or bar m, in combination with the tube-board c and bellows-valve 0,arran ged and adapted to operate as described, whereby the said roller or bar on will automatically descend and open the valve 0 when the perforated music-sheet is passed under the bar or roller and away from it, as and for the purpose set forth.

In testimony whereof I have affixed my Sig nature in presence of two witnesses.

GEORGE W. TURNER.
